1. A coupled torsion beam axle type suspension system (CTBA), comprising:
trailing arms respectively coupled to opposite ends of a torsion beam; and a vehicle body-engaging unit provided in a front end portion of each of the trailing arms and engaging the each of the trailing arms to a vehicle body, wherein each vehicle body-engaging unit includes:
a trailing arm bush that is coupled to a front end portion of the trailing arm;a rotation link disposed in front of the trailing arm bush and engaged thereto in a width direction of a vehicle;a slider rotatably connected to a front end portion of the rotation link, and slidable along a length direction of the vehicle body; anda connection link pivotally connecting an outer end portion of the rotation link and the vehicle body, such that an instantaneous rotational center point of the rotation link is formed outside of the rotation link in the width direction of the vehicle.
